Review on High-Capacity BAOFENG BL-5 Rechargeable Batteries - Compatible With UV-5R BF-8HP, UV-5RX3, RD-5R, UV-5RTP, UV-5R+ And UV-5X3 Radios - 3800MAh Extended Battery Pack (2 Pack) - Made In The USA by Hanson Kendrick

I ordered this 2-pack battery kit from Mirkit and found them to work perfect and fit my UV-5Rs without any issue. I have 3 UV-5Rs, and I had ordered the standard BTECH one for my first UV-5R. That battery didn't work at first, and wouldn't seat properly on the radio at the contacts. It turned out that there was a small piece of plastic (residual from the manufacturing process) that was blocking the contacts, and it didn't take much to clean it up. That batter worked fine after that, but these two Mirkit edition batteries had no problems at all right out of the box.Perfect fit and so far they are working just great.
